History
James O'Shaughnessy Cornerstone Value is a value investing strategy presented by US fund manager James O'Shaughnessy in his 1996 book, What Works on Wall Street. His extensive backtesting found that value investing works particularly well with large capitalisation stocks with above average sales and cashflow, high levels of share liquidity, which were then sorted for the highest dividend yield. O'Shaughnessy said: "Generally speaking, when things are going against you, as they inevitably will, you have to stick to the underlying strategy? Only by doing so will you be around for when it comes rebounding back." He found that this value strategy produced an annual compound return of 15% between 1954 and 1996, compared to 8.3% for the S&P 500 index. O'Shaughnessy has continued to conduct detailed analysis of Standard & Poor's Compustat database to identify the most effective investing strategies. more »

The sales figure gives a sense for the scale of a company, although companies can have very different profit margins depending on the industry and state of the business, so this may not bear much relation to the earnings figure. Some however argue for the importance of sales, since sales figures are less easy to manipulate than either earnings or book value.

Operating cash flow - or cash flow from operating activities - refers to the amount of cash a company generates from the revenues it brings in, excluding costs associated with long-term capital investment. It is similar to operating profit but excluding non-cash items and accruals.
